Yes, it is true; this is a method to obtain salt from sea water.
Fractional distillation of the liquefied mixture is one possible method.
You would obtain the mass of the liquid while it was in the measuring cylinder and then, from the combined mass, you would subtract the mass of the cylinder to obtain the mass of the liquid.

Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 mL, 25 mL, 50 mL, or 100 mL and up to as large as 1 or 2 liters.Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.In other words, holding the graduated cylinder at eye level, the bottom of the curved surface of the liquid (called the meniscus) is where you read off the mark on the graduated cylinder to determine the volume properly.
You can use a graduated cylinder or a pipette of 50 mL.
I suppose it depends upon the molarity (concentration) of the HCl. Ask your teacher or lab instructor for sure, but I would immediately place the graduated cylinder with the acid into a storage vessel of some kind, wash my hands thoroughly, then obtain new HCl and cylinder and start over. Do NOT just dump the HCl down the drain, unless it's really dilute. Again, ask your instructor for clarification.
